"Open source developers have had to think on their toes and patch the programs that Microsoft has (often times) intentionally broken." This is definitely true

"Open source developers have had to think on their toes and patch the programs that Microsoft has (often times) intentionally broken." This is definitely true for members of the Samba team, but open source development does not necessarily involve cleaning up Microsoft's mess. It also does not necessarily involve a work ethic of any kind, good or bad. I'd suggest hiring hardworking and quick-thinking developers; I don't think work in open source precludes laziness or dullness.
